Diagnosing Heaters That Don’t Turn On

The last thing you want your heater to do is not to work when you need it the most. Heating problems are fairly common in households and buildings alike, but it’s not that difficult to diagnose provided you know the process.

First, check if the thermostat has power and make sure it’s set to the heating function. The temperature setpoint must also be higher than the ambient temperature in the room. Set the fan on the thermostat to “on” just to be sure.

Check the Power

Next, you will have to check the power. What most homeowners don’t realize is that even gas-powered heaters use electricity and your heating problem may, in fact, be an electrical problem. Check the circuit breaker and make sure that the heating equipment isn’t tripped.

You’ll then want to inspect the systems power cords for signs of damage and replace the ones that have any tears or cuts. Finally, check the heating system’s control board for burn marks as these are clear signs that the system may have sustained an electrical short.

Inspect the Condensate Pan

The condensate pan is a forgettable part of the heating system and is often the source of your “no heat” problems. If its full, then the heater won’t turn on. You simply need to drain the reservoir to fix this. Make sure to check the condensate pipes for blockages so that the pan doesn’t fill and stay full.

I'm a relatively new home owner. I'm still in the process of building my list of trusted technicians for various household appliances. Lone Star Comfort Aire will be my first choice for all HVAC issues going forward. Specifically, Nathan Raglin. Mr. Raglin was extremely courteous, knowledgeable, and professional. My issue was fixed quickly and for a fair price. A different company told me I needed an entirely new system and that my system was 13 years older than it actually is. Mr. Raglin did not try to pressure me to buy anything I didn't need. He did not hesitate to answer my questions or treat me poorly for asking what were undoubtedly some amateur questions. I don't want my HVAC system to be in need of repair, but at the same time I want to give Mr. Raglin more business. For now, I hope a 5-star review will do.

What a great business. Greg called ahead of appointment time to let me know he was on his way. Fixed my air in no time. Did not try to sell me anything I didn't need. This is now my go to air repair. He went above and beyond for me. I thank you!

Nathan Reglin is the best a/c man! He fixed my a/c in no time, didn't try to over charge me and helped me save money by installing my attic step cover! Not only did this cool my closet off but my bill dropped by $20 dollars for the last 3 months! We will be life long customers of his!

I've had great service from this company for over 20 years. They offer 24 hour service which I need for my rental properties. They even came out on Christmas Day during a major cold spell. I wish they were available in Indiana and Florida for my other properties. The owner runs his business honestly based on Christian principles. I highly recommend this company.
